The strap feeding mechanism is best shown in Figs. 8, 9, 22, 23 and 34.The general layout of the entire pneumatic mechanism is best shown inFig. 34.

Summary of boa: strapping procedure Referring to Figs. 1 to 9, theunstrapped box B is pla-ced in position manually on the anvils A. Theanvils A are operated by toggle mechanism G best shown in Figs. 14 and21.

The box B itself (see Figs. 1 to 10) consists of the bottom 50, the sidewalls 5| and the end walls 52. The box ends or margins 52 are somewhatthicker and stronger than the bottom 50 and the side Walls 5I (see Figs.l to 10).

The entire box structure B is to be reinforced by the metal strapping S,which is to be wrapped l:around v:the Send walls 52 .and .over .themargins -or edgesof thefbottomf andthe sidewalls 5|,

.which embrace and holdsaid :end walls 52. The

.straps -S fare fed to theboxsby the strapffeed mechanisms The :straps.Szusually consistof two/continuous strips 'of .thinsheet'lsteel :rolledthe end Walls 52 'of theboxB. The first nail H vis then inserted by thenailing device I which is .moved to a p'osition'overthebox endsy52 andthen withdrawn by the mechanism (seealso Fig. 28) after the iirstnailHIsee Fig. 4) `has been l. applied. Then Ithe anvils A are withdrawnby the toggles C, as indicated-iny solidv line position `in Fig. 21. Thebox Bfis thenyfree to be turned by the gripping jaws F andgG'.'

The box B is then yrotated while clamped rbe tweenvthe `reciprocable jawG and rotatable jaw A F by rotational drive mechanism N (seeparticularly Figs. 13 and Y21). The box is rotated ka kfull 360 by theclutch mechanism O (see particularly Figs. 1.2 and 14), the operationjofwhichiisinitiated by thefoot treadle P.

When the straps .S have been wrapped around the ends'of the box B,thesecond nail Q is driven intov positionas showninFigs. 8 and'9,and'then the strapping S is cut. The cutting Amechanism Rof Figs. 28to33 is actuatedintothe position of'Figs. 7 and V3,0 bythe motors Utocut the end of the strap'S. During the final nailing and cutting, thestrap feedmechanisms have been withdrawn to theposition of Figs. "7 and22. The v strap feed mechanismsare operated by the pneumatic motors 'Ra(see particularlyFig, 8).

The nailsv H and v`Qare lfed .alternatively in proper sequence by thenail feeding mechanism T asbest shown in'Figs. 35 vto 38.

Onlyone nailHorQ is vinpositionto be driven into the strap S upon eachvoperation of the hammers 506 ofthe nailing mechanism I y(see Figs. 22,23, 25 and'2'1) One nail H isdriven at the beginning of the attachmentofthe strap S Figs.'4and 1 8) 'and the second nailQ at thecon- 'clusionof the strapping operation ('Figs 8, 9,.

22 `and 23).

` Pneumatic-system Referring particularlyto Fig. 34, the various motorsJ, K, M, Ra and U are'shown as being actuated from a central pneumaticsource a1- though it is obvious that they may beroperated by hydraulicmotors, rotary 4electric'rmotorsr orsolenoid motors oi' mechanicallyvices, such as cams or screws. l

and 91..withdrawing the shear mechanisms R. When., the handle 15 ismoved in direction 22|. the ports 14 and 11 on one side and the ports 16and 19 on the other side will be connected in pairs. If desired, handles61 and 15 may be provided with return springs (not shown) to return themto the position shown in Fig. 34.

, The branch 65 from the main line 62 leads to The valve..66 has acylinder |4|, a double piston |42 on the piston rod |44. The piston rod.|44 has a collar |45 against which reacts the spring |43 biasing thepiston lto the right. The end |46 of the. piston rod |44 will be pressedagainst and move-.with the lever 601 pivotally mounted at 606 (see alsoFigs. l2 and 14). 'I'he lever 601 at its upper end carries a roller orfollower 622 which rides on the-cam .62 The cam 62| has a recess 623.The cam 62| is driven on the shaft 620. The shaft 620 will be rotated360 each time the treadle P is depressed. This will turn the "box Bthrough 3605 through the mechanism N and clamping devices F and G.

Asthe cam 62| rotates and lever 601 oscillates, the ports |50 and |5|(see also Fig. 12) alternatively will be connected to the inlet ports|39 and A|40 or to the outlet atmospheric port |53 which leads to theatmosphere. The ports |50 and |5| are connected to the lines |55 and|56. The lines |55 and |56 are respectively connected to the lines |51and |56 and to the lines |59 and |60 which lead to the ports |6| and |62and to the ports |63 and |64 in the cylinders |65 and |66; y

-The cylinders |65 and |66 receive the pistons |61-and |68 which havepiston rods |69 and |10 passing through thestuing boxes |1| and |12 (seealso Figs. l1, 12` and 13). The piston rods |69 and |10 are connected bythe swivel links |13 Iand |14 to the toggle mechanisms C which atuatethe anvils A (see also Figs. 14 and 21).

In the position shown in Fig. 34, the pistons |61 and |69 will havemoved the toggles C so as to elevatethe anvils A. In this position, thepiston |42 of the valve 66 has taken a position Where the ports |40,l|63 and |64 will be in communication and the roller 622 on the lever 601will benin the recess 623. The ports I6|, |62, |50 `and 53'will also bein communication to the air, exhausting or releasing any pressure onleft side of piston |68 and right side of piston |61. When the cam 62|rotates, the piston |42 will be moved to theright from the positionshown in Figure 34 to connect ports |39, |50, |6| and |62 on thepressure side and ports |53, |5|, |63 and |64 on theatmospheric side,collapsing toggles C and lowering anvils A so thatthe box B may rotateas' shown in Figures 2l and 43.

The valve 60 for controlling the movement of A the anvils is directlyconnected to the main line leads to the inlet port |98 of the valve 59.The valve 59 has a handle |99 which is designed to operate the rotaryelement 200 to connect the inlet port |98 alternately to the port 20|and line 203 or the port 202 and line 205. The lines 203 and 205 fromthe ports 20| and 202 respectively lead to the ports 206 and 201 of thecylinder 208 of the pneumatic motor J (see also Figs. 13, 21 and 42) Thecylinder 208 is provided with a piston 209. The piston 209 has a pistonrod 2|0 extending through the stufiing box 2| The piston rod 2 I0actuates the rod 2 6. The rod 2 8 passes through and turns with the hub2 2 receiving the sprocket or toothed wheel 2| 3. The wheel 2|3 isdriven by the chain 2|4. The rod 2|6 is connected to the reciprocableclamping head 340 carrying the clamping member 330.

In the position shown in Fig. 34, the valves 59 and 60 will connectports |93, |94, |98, 20| and 206 and the air pressure will move thepiston 209 to the left, pressing the clamping member 330 against the boxB.

Turning the handle |99 in the direction 250 a distance of (Figure 42)will connect ports |93, |94, 200, 202 and 201, removing the clampingmember 330 from the box B after strapping is completed.

The line 62 (Figures 34 and 41) also communicates with the branch line64 which leads to the port 222 of the valve 58. The turning valveelement 223 is operated by the handle 224 either to connect port 226 ofvalve 58 to the atmospheric port 225 or to the inlet port 222. The port226 connects with the line 221 which splits into the lines 228 and 229.The lines 229 and 229 lead to the ports 230 and 23| of the cylinders 232and 233. The cylinders 232 and 233 have the outlet ports 234 and 235 andalso receive the pistons 236 and 231. The pistons 236 and 231 havepiston rods 239 and 239 which extend through the stuiling boxes 240 and24|.v The piston rods 238 and 239 actuate the strap feeding mechanisms E(see also Figs. 6, '1, 8, 9, 22, 23 and 24).

The valve handle or lever 224 (Figures 36 and 41) is biased by thespring 242 against the direction of the arrow 243. The lever 224 isconnected to the rod 244 at the pivotal connection 245. The rod 244 inturn is connected by the pivotal connection 246 to the bell crank lever241. The lever 241 is pivotally mounted at 248 and is actuated by thestud member 249. The stud member 249, on each reciprocation of thecutting devices R at completion of the strapping to clear the box, willmove the bell crank lever 241 in the direction 252 to the position shownin Figure 4l.

In the operation of the strap feeding devices E, the pistons 236 and 231of the motors Ra will rst move rearwardly upon insertion of the nalnails Q. After cutting of the completed strapping S by the 'cuttingdevices R, the feeding devices E will be movedforwardly to feed them1t1a1 ends 53 of the strapping over the ends 52 of the new box BVplaced on the anvils A.

when the beu lever 241 is actuated by the stud 249 in direction. 252,moving the rod 244 downwardly (Figure 41), the rear ends of thecylinders 232 and 233 through the ports 230, 23|, 226 and 225 will` beconnected to the atmosphere. The devices E will ,then be moved totheright by return springs 362. As soon as the shearing mechanisms R haveagain been Withdrawn by the cylinders U, the feed devices E will bereturned by pneumatic pressureA being. applied Machine frame structureAs shown in Figs. 11,' 12, '13 and 14, the left and right uprightmachine frames X and Y are mounted on a base or table 260 which may bemounted upon the floor or upon a foundation by the legs or depresseddepending marginal portions 26I (see particularly Fig. 14). The frames Xand Y have the cross plates 258 and 2580.. Extending upwardly andmounted upon the left cross plate 258 are the U-cross section side framemembers 262 of the frame structure X. The ybottom cross plate 258connects the side members 262 which has the outwardly inclined lowerportions 263 (see Figs. 11 and 13). The lower portion of the frames 262fit between the tracks 264 (see Fig. 13). Between said frames 262 ispositioned the lug 266 receiving the threaded opening 261.

Through the threaded opening 261 extends the screw 268. The endl 269 ofthe screw 268 is carried by the central portion 210 of the yoke 21|. Theyoke 21| is mounted upon the table 260 (see Fig. 11) by the'bolts 212.The screw 268 is actuated by the hand wheel` 213 on the shaft 214. Thehand wheel 213 drives the worm 216 which meshes with the gear 211 whichturns the screw 268. 'I'he screw 268 extends through the structure X andis also threaded into the sleeve 280 tting in the cradle 28| inthe lug218 (see Fig. 11).

By turning the wheel 213, it is possible. to move the frame structureXreither to the left or right as indicated by the double arrow 219 ofFigs. 11 and 13 to accommodate diiferent sizes of boxes. Extendingbetween the side members 262 are the transverse member 3|| (see Figs. 17`and 21) carrying an anvil A, the transverse member 325 carrying thereciprocating, nailing and cut-v ting mechanisms I and R, the transversestruc- .l

tures 331 and 338 (see also Figs. 17 and 21) carrying the rotatable-jawmechanism F and alsothe top plate 441 (see Fig. 12) carrying themechani'- cal drive'mechanism V. :At the bottom of the' frame structureX is pOsitioned the U-shaped cross brace 294 having side legs 295attached to` the side members 262 (see Fig. 14).

The fixed frame structure Yl consists of. the` four U-shaped cornervertical beams 290 and 29| which are tied together by the cross bars 292and 293 (see Fig. 13). The vertical members 290 and 29| are connected bythe base plate 258a. The

structure 3| l carrying the right hand anvil A (see Fig. 13) alsoextends between and is mounted on the vertical channels 29|. There isalso provaided the angle braces 32| with the side legs`322 (see Fig. 12)and thecross tie member 323 held in position by the bolts 324. f

The rotary'mechanismrN and the reciprocable jaw G and its pneumaticmotor J are mounted on the transverse members 292 and 35| (see Fig. 21)forming part of the structure Y. The nailing mechanism I and cuttermechanism R are supported on the U-frame member 325 of the framestructure Y having the side legs 326 on" which is'mounted the plate 54|(see Fig. 12). The top plate 441 supports mechanism V.

the mechanical drivingl Anvil structure Thevv anvil structures `A (seeFigs.. 11 yto 14, 17 and 21) include the vertically sliding box-supportY members 300 which are connected by webs 30| to the vertical platemembers 302 which are provided with the dovetailed guide members 303/(see particularly Fig. 13). These guide members 303A engage thedovetailed guide projections 304 (see Fig. 13) extending outwardly fromthe plates in the central portions 1302a ofthe plate members 302. Thevertical slider plates`305 arey also provided withy the dovetailed guideportions 308 (see Fig. 13) f which engage the corresponding projec-ytions 309 on the ixed plate 3|0 which is mounted on the cross beammembers 3| n (see Fig. 21) of the frame structures X and Y. The plates305 (see Fig. 17.) carry the outwardly projecting lugs 3|2 which projectthrough the slots 329 in the plates 302. Between the lugs3l2 extendthepivot rods 3|3 carrying the upper ends of the links 3|4 (see Figs.14, 17, 21 and 34). The lower ends ofthe links 3|4 are pivotallyconnected to the armsn3|5bythepivot rond 3|6. The links 3|5 at theirlower ends are connected tothe pedestals with Fig. `34.- Fig. y21 showsthe uppermost and loWermost positions of the slidablyoperated anvils Akrespectively in dot and dash and solid lines.

Rotatalble clamping members The iixed and movable clamping heads F and Gare shown in detail in Fig. 21, and are also shown diagrammaticallyy inFigs.' 1, 2 `and r42.

They are also shown in the assemblage in Figs. .11,v

12 13 and 34. The fixed head vF has a squarev or rectangular contactface element 330 (see Fig.. 21a) which is'roughened or knurled at itspe` i riphe'ry 356 and slightly recessed at 351 to contact and clampther edges or Walls of the box B. The

ycontact platev 330 may, if desirable, be of such size and shape so thatit will only contact rthe endsof the bottom and side walls 5| ofthe boxin which case replaceablecontact plates 330 would be used for eachdifferent width and depth. of box B. The plate #330 is carried by thediskj 33| (see Fig. 21) which inturn is carried by thel disk 332.

`VExtending to and through the disks 33| kand 332 is thel hollow shaft333 rwhich has bearings in the'bearingmembers 334and 335. Thebearingmembers 334 and 335 arev mounted upon the plate 336 having the dependinglweb 358. The

plate ,'3367is supported on thef transverse frame members 331 and 338.Theframe members331 and 338 extend between the side structures 262 ofthe irameX.

The reciprocable head G has a rectangular contact plate 330, thev insideface of which is knurled as'shown at' 356 in Fig. 21a. The plate 3,30 ismounted on the disk 340. The base of the disk 340y has Isliding pins 34|which fit into openings y342 in the rotatable disk member 343.y The diskmember '343 is'carried on the rotatable tube or'.v sleeve 346 whichturns in the bearings 345 and 348. lThe sleeve 348 is xed and turns withthe sprocket wheel 2|3 by the key 2|1. The wheel 213 is turned by theychain 2 |4 (see also Fig. 34).

Extending through the bearing element 345, the wheel 2 I3 and therotatable sleeve 346, is the shaft section 2 I6. The shaft section 2 |6is permanently attached to the disk 340.

The piston rod 2|0 is connected to the piston 209 in the cylinder 208and is connected by thrust bearing 2|5 to the rotatable shaft section2|6. The cylinder 208 and the bearing structure 348 are fixed upon thetable 349 which has a downwardly depending web r flange 350. The flange350 is bolted to the cross member 292. The table 349 is also mounted onthe structural member 35| of the frame structure Y.

It will be noted that the rotary jaw structure F is non-reciprocable,while the rotary jaw structure G is reciprocable. The jaw G is held inrotational position in respect to the rotary head 343 by the engagementof the pins 34| in the openings 342.

The reciprocable jaw or head G will normally be held in retractedposition by the coil springs 352 which extend between the ears 353 and354 respectively on the plate members 330 and 343 (see Figs. l, 2 and3).

Strap feeding mechanism The strap feeding mechanism E is best shown inFigs. 22 and 24, although it is also shown in smaller scale in Figs. 6,1, 7a, 8, 9, 12, 14 and 34.

The strap feeding mechanism E. consists of two side plates 360 (see Fig.8). The plates 360 are pivotally mounted by the rod 36| (see Figs. 6 and14) upon the frame structures X and Y.

The plates 360 are biased by the springs 362 in direction of the arrow363 (see Fig. 14). The spring 362 extends between the stud 364 attached'to the structure E and the stud 365 attached to the frame structure X orY. The upper portion 366 of the structure Eis provided with anadjustable stop bolt 361 (see Fig. '1) The bolt 361 (see Fig. '7) isprovided with the lock nut 368. The head of the bolt 361 will be stoppedagainst the lugs 369 on the frame structures X and Y and limit movementin the direction 363. Between theplates 360 (see Figs. 8, 22 and 24)extend shafts or studs 310, 31|, 312 and 313 which carry the rollers314, 315, 316 and 311 to give a reversed bend to the straps S.

The dog 318 is pivotally mounted at 319 on the plates 360. The dog 318has a jaw 380 to operate against the fixed jaw 38| and grip and preventretrograde movement of the strap S. The dog 318 is biased by the spring382. The ends of the spring 382 are attached to the dog 318 and to thexed stud 383.

The upper rollers 314 t into grooves 314a on the lower rollers 315 (seeFig. 7a). The other pair of rollers 316 and 311 are of the sameconstruction. The rollers 314 to 311 are freely rotatable. When thestrap S passes between the rollers 314 and 315 and rollers 316 and 311,it is given a reverse bend or downward bulge to cling and closely to fitagainst the edges or margins of the box B by reason of its ownresiliency. The strap S along each side o f the box B will be bowedtoward or curved toward the box B and closely hug the box B as indicatedby the completed S in Fig. which has been removed from a strapped box B.When the motors Ra retract the strap feed structures E by the shafts 238and 239 (Figures 34 and 41) connected to the blocks 390 and 39|, thedevices E will pass over the straps S without movement of the straps S.The upper ends or jaws 380 of the dogs 318 will move in the direction392 (see Figs. 9 and 24). On reverse movement, however, the jaws 380 ofthe dogs 318 will grip the straps S and move the straps S forwardly sothat. their ends 53 will assume positions as indicated at 53 in Figs. 1,2, 9 and 24.

` When thestraps S are withdrawn through the feed devices E uponrotation of the box B, the dogs 318 will permitmovement of the straps Sin the direction 392.

' Strapping supply The supply of strapping material D is shown in Figs.12, 13, 14 and 17.

As indicated, the supply D consists of the large reels 400 having sidewalls 40| which are mounted on the stud axle 402 attached to the wall bythe fianges 403. The stud axles 402 fit into the bearing cups 404 on thepillows 405 on the upright frames or standards 406 having the baseflange 401 attached by the bolts 408 to the table 260. The two reels areconnected by the connecting shaft 409 (see Fig. 13).

It will be noted from Figs. 12 and 1'7 that the strapping S will comeoff the reels 400 with the upwardly convex curvature. After it passesthe devices E it will have a downwardly convex struc'- ture as shown inFig. 10a. This downwardly convex curvature will cause the strapping S tohug the box B most closely.

Nail feeding mechanism l The nail feeding device I is best shown inFigs. 11a, 15, 16 and 35 to 38. The feed head T has a shaker pan 420(see Figs. '11a and 15,) to which is attached flange 42| of thedownwardly ex-V tending double pivot mount lugs or ears 422 (see Figs.11a and 12). Between the ears 422 is'received the ear 424 of theuniversal connection member 425. The pivot rod 426 assures swivelmovement between element 425 and the ears 422. The element 425 hasdepending ears 421 between which is received the eye 428 of the rod 430.The pivot pin 429 extendsl through the eyes 421.

The lower end of the rod 430 (see Figs. 11a andv 12) has an eye 43|received between the ears 432 of the yoke or eye 434. The pivot pin 433extends through tlie eye 43| and the ears 432 forming a. pivotalconnection. The yoke or eye 434 is bolted at 435 to the end 436 of thecrank 431. The crank 431 has an eye 649 (see Figs. 11a and 12) fitted onthe shaft 654. The shaft 654 passes through the disk 653 ('see Fig. 11).The shaft 654 is driven from the motor 650 (see Fig. 11) through thereduction gear boxA 652 to give 'an oscillating movement indicated bythe arrow 438 of Fig. 11a to the pan 420.

The tray 420 is provided with an oscillating connection 439 to theslotted guide member 440 (see Fig. 11a) The slotted guide member 440 issupported by the link 44|. The link 44| is connected by the slottedopening Y4|9 and pivot 442 to the slotted member 440. The lower ends ofthe links 44| are connected to the ears 444 by the pivot pins 443. Theears 444 are mounted on the plates 445 supported by the vertical members446 (see Fig. 12) from the top plates 441 of the frames X and Y. Theslotted member 440 (see Fig. 36) has the side walls 448 and the bottom449 having two nail guiding slots 450 and 45|. The bottom 449 whichguides the heads 452 of the nails 453, which are lined up and guided bythe bottom section or guide bar 455. The slot 456 will enable insertionof tools to the line up nails 453. The nails 453 will slide down in thedirection 451 until they hit the disks 458 and 459.

These disks 4,58 and 459 are rotated upon the stud shafts 460` extendingthrough the bearing mem-1 bers 46| in the structure y462 forming thefront wall of the slotted member 440.

The collars 464 of thebevel gears463 are fixed on the pins 465 on theupper ends of the shafts 460. The bevelled gears 463 are driven by theintermeshing bevelled gears 466 kwhich are fixed on the shaft 461 whichhas bearings at 468 in the extensions 469 of the side walls 448 (seeFig. 35). y

The disks 458 and 459 are providedwith recesses 410 and 41| large enoughto receive the heads 452 of the nails 453. The recesses 410 and 41| arepositioned 180 apart as indicated best in Fig. 36. When the recesses 410or 41| come opposite the slots 450and 45|, the heads 452 of the nails453 will slip into the recesses 410 and-41| with the shanks fallinginto` the open space 412 extending around the parts 413 forming part ofthe structure 414 (see Figs. 37 and 38). rPhe nails 453 will then becarried around by the rotating members 458 or 459 with the next nailbeing stopped by the unrecessed edge 415 of said disk members 458 and459. When the, nails 453 have vbeen carried around 180, they 4will fallinto `the recesses 416 in the structure 411 forwardof the structure 414.1 I

The structure 414 formingpart of the slotted member 440, is providedwith the flange member 418 (see Figs. 11a, 3'1 and 38). The flange mem.-bers 418 rest upon the ange members 469.,r The flange members 480 formpart of the bracket 48| connected by the flanges 482 upon the structure483 (see Fig. 11a) connected to the frames X and Y. The* nails 453 dropas indicated by the dot and dashlines 490 in Fig. 3'1 intothe funnel 49|through which the nails 453 will pass indicated in the direction byarrow 492.

The shaft 461 (see Fig., 16,) `is vdriven by the sprocket wheel 494iixed to said'shait by the col-7 lar 495 and the pin 496. gl The chaindrive 491 is operated from thesprocket 64| driven by the .gearV 639 onthe shaft 640 (see Fig. 15).' The gear 638 on the main crankshaft 814drives the gear 639. The shaft 614 is driven bythe mechanism V shown inFigs. 12 andrlZa, as'will be more fully described subsequently.

The shaft 461 willV only be-rotated each time the nailing mechanismslhave been moved nwardly by the motors `M' of Fig. 34 over the end walls52 of the box B. As they nailing mecha-v` nisms I have beenfmovedinwardly, the Afirst nail H or the last nail Q to be driven will alreadyhave been dropped into the'recess 416 and one of the recesses 410 or 41|will be opposite the slots 450 or 45| and have received the nexty nailThen when the nailing mechanisms I have moved into position over themargin of the box` B by motors M, the shaft 461 will be operated to,turn the disks 458 and 459 by one-half revolution,k

operated by the motor 650 throughthe reduction gear box 652 and thecrank 431 to feed nails 453 into the slotted member 440.

N ail applying mechanism The funnels 49| are supported in the eyes 498by the shoulders 499 (see Figs. 37 and 38). The

. V14 eyes 498 are positioned at theends of the brackets 500 attached tothe frames X and Y., Below the funnels 49| (see Figs. 25 to 27) arepositioned the tubular conduits 50|. Thefconduitsf50| have exibleconnections 5|6 to the lower funnels chutes 502. The chutes 502 haveinwardly clined portions 503 and upwardly. extending sleeves 504 whichreceive the bearing 5|4 for the hammer rods 506. The hammer rods 506have the enlarged heads 501 which fit into the slots 508 above theinturned members :509. The slots 508 arev in the base structure 5|0at'the bottom of the reciprocating heads W. The Abase* struc: tures 5|0have the dovetailed portions 5||(see -Figs. 25 and 27) which fitinto/recessesv 5|2 in the members 5|3. The bolts 5|4a (see FigL'Z'?)hold the members 5| 0 and 5|3 'together in' a'd` justed position. e l ny e At the lower portion of the inclinedtubefs503 arevpositionedkseparable jaws 520. and 52| (fseef Figs. 25 and 27) which are pivotallymounted on the ears 522 and 523 yon the extensions 524.
